IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 53,912, dated April 10,1866.

To all 'whom 'it may concern: l

Be it known that I,EDWIN P. WHI'IGOMB, of the city of Coldwater, in the county ot' Branch, in the State ot' Michigan, have invented certain new and usei'ul Improvements in Ghurns; and I do hereby declare that the following is a full, clear, and exact descripaccompanying drawings, making a part of this specification, in which the figure shows a vertical section through the center of the churn, the diamond-shaped reversed-motion beaters, the bevel-gear, and frame for giving motion to the revolving dashers.

The'object of my invention is to make the most practical and etcient churn for making good butter in a northern climate at all seasons of the year.

My invention consists in combining with a water-chamber which surrounds the sides and bottom ofthe vessel or metal can reverse-Inotion diamond-shaped right-angle blades or beaters and the frame which supports the To enable others skilled in the art to make and use my invention, I will describe it more fully, referring to the drawings and t0 the letters marked thereon.

I make the tub AAin the ordinary manner, inside ot' which is placed a can, B B, of sheet metal, it being supported by a flange, I) b, which surrounds the openin g at the top, tittin g in the recess a a in the tub A, so that a space or chamber, C C, is left all the way round between the tub and can, as also in the bottom. This is for the purpose of putting in water of any desired temperature, either hot or cold, to temper the cream as the season requires, this being necessary to make a good quality ot' butter, both in summer and in the winter season.

On one side ofthe tub A, at near the top, I have a funnel, c, and a'n opening to putin the water, and at the bottom I have an outlet, e, or spigot to draw oft the water from the chamber C, and also another stop-cock or spigot, d, which communicates with the inside ofthe can, for the purpose of drawing ot't the buttermilk as it is being separated from the butter, and also the rinsing-water when cleaning the churn.

The apparatus for agitating the cream is constructed by placing square pieces of hard wood, f f f f', ina vertical position onto horizontal diamond-shaped arms g g, so that one corner is notched into the arms on reverse sides, thus presenting two inclined edges to cause friction as the dasher revolves. The two outside beaters,f'f, extend down to the bottom of the can B, while the other two stop at about half-way down. Below this beater is placed on a shaft or rod, 7c, which has its bearings in a socket, l, on the bottom ot' the can, another beater, similarly constructed, with horizontal arms h h and vertical diamondshaped beaters v5 i t' ,'all of the same length, which are made to revolve in the opposite direction to the top beater, they working inside of the long beaters ff'.

The top dasher is secured to a tube or hollow shaft, D, with the rod or shaft k passing through it, extending from the socket Z up to the top of the frame E, which is so constructed as to make a support for the crank-shaft F and bearings for the journals ot' the vertical shafts D and It at the top, on which are the bevel gear wheels to operate the beaters, which, by connecting with the bevel-gear I, on the crank-shaft F, the beaters turn in opposite directions.

I do not claim the double or reverse motion, neither do I claim the water-chamber which surrounds the can of sheet metal, as they have been known and used; but,

Having thus fully described my invention, what I do claim as new, and desire to secure by Letters Patent, isl The combination ot' the frame which supports the gearing, the reverse motion diamond-shaped right-angle blades or beaters, as

described, with the space or water-chamber' which surrounds the churn, substantially as herein set forth.

Subscribed to on this 31st day of January, 1866.
